workspace command: inline a variable

[NJichev]

A workspace command that inlines a variable.

defmodule Example do
  def run(argument) do
    var = String.split(argument, "\n")
    DoSomeOtherThing.run(var)
  end
end

Hovering var with the cursor on both places and running the workspace command should result in:

defmodule Example do
  def run(argument) do
    DoSomeOtherThing.run(String.split(argument, "\n"))
  end
end
